a: \(M=-\dfrac{3}{4}\left(\dfrac{2}{11}+\dfrac{9}{11}\right)+2+\dfrac{3}{4}=-\dfrac{3}{4}+\dfrac{3}{4}+2=2\)
b: \(=\dfrac{1}{4}:\left(1+\dfrac{5}{16}-\dfrac{3}{2}\right)+1=\dfrac{1}{4}:\dfrac{-3}{16}+1=\dfrac{-4}{3}+1=-\dfrac{1}{3}\)
c: \(=\dfrac{14}{9}-\dfrac{1}{2}\cdot\dfrac{4-3-1}{12}-\dfrac{4}{9}=\dfrac{14}{9}-\dfrac{4}{9}=\dfrac{10}{9}\)
